Abstract:
Flexible bronchoscopy is useful for confirming an endotracheal tumor. However, observation of the distal end of the tumor is difficult because of the presence of the lesion itself. Here we describe a technique that we termed "bronchoscopic turned around procedure," which can be used to observe the distal extent of the lesion using an ultrathin bronchoscope. The scope is passed distal to the endotracheal tumor and is flexed upward by 180 degrees in the trachea for full visualization of the distal extent of the lesion and the airway anatomy. We found this procedure to be an effective technique to assess surgical candidates by confirming the surface structure of the tracheal lumen, which cannot be obtained by computed tomography or virtual bronchoscopy.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
